My ipod has had trouble with battery life. I will let it charge to full capacity, then walk out with it and within 5 minutes the battery bar falls to 75%, then 50%, then back to 75%, then 25%, etc. Then recently it kept freezing every time I selected a song. It was so bad I wasn't able to do anything but let it sit and come back the next day and try again. Today I used it and it would just shut off each time I played a song, then it showed something saying I need to do a fix or find an update or something, I can't remember. I'm currently recharging it again until it's full. Does it sound like a battery issue, or maybe a virus that was downloaded somehow to it, or both? Is there any software fixes out there if it is a software issue?
